Thanks morzh,
The speculation on the cap was just that, speculation ;). It is very likely that they will return to leaky, and with whatever internal degradation may have taken place - corrosion products and salts/acids evolved in the paper over time - the failure would probably return sooner rather than later. I'm certainly not advocating this as a restoration practice!
The job of rewinding certainly is a challenge. I'm now finishing up the O/P transformer. Primary is done (#35 wire, 20 layers of 140 turns each with center tap). The secondary will be next. That is 18 AWG - incredibly beefy considering the voice coil of the speaker!
In Episode 6, "Coneheads" I'll cover restoration of the speaker.

I don't hold with furniture that talks.
